Question "Carrier Heat Pump"
We have 2 Infinity Heat pumps, one for upstairs one down. New construction units just turned on 3 weeks ago.( house not complete yet). They worked fine as we allowed them to run 24 hrs. to check them out. Turned them off. Yesterday we noticed that the thermostat (1st. floor) was not light up. Pushed on and nothing, checked breakers all ok. Decided to check 2nd. floor unit, turned on it would heat but no air coming from vents. The air handler for this one is in attic. The temp. in house was 78 so I pushed the thermo up to about 83 to try and get the blower to come on, nothing ONLY the thermo showed that the auxiliary heat was on. It was 66 out side, should the auxillary come on when it is warm out side?
I am going to call Carrier and have a Tech. come out BUT any idea what could have happened to them. They were tuned off as no need to run up electric bill in a house not yet complete. I though the thermostat would tell me problem but I don't know if it is hooked up right as it did not tell me of a problem. NO Lighting storms or power surges that we know of. How can something break just siting there. We would like to do some checking befor the HVAC man comes. Thank you in adance |

Re: Question "Carrier Heat Pump"
The heater will come on if the indoor temp is below the heat set point. Outdoor temp generally does not control/lockout of the indoor unit. If you aren't familiar with the infinity contols, it's a Carrier thing. I don't how to get into the diagnosis setup. But with a little internet research, I'd handle it. As Nick Tech says, "I digress".
If you set the heat point several degrees above the actual temp, the aux heat will come on quickly. It's weird that you say heat comes on but no air. Probably a bit late, but I would turn the fan on at the fan switch at the t-stat. Check to see if blower operates. It is likely a question of correct control voltage wiring. |
